Most of the useful things in milk are there because we artificially added them in. There is no real reason for this, it's just what we have been doing for a long time

You can get all the vitamin D you need from just 10-30 minutes midday a few times a week.

Also, cow's milk doesn't naturally contain vitamin D. Vitamin D is added to cow's milk and is even required by law in some countries (Canada and Sweden). Might as well just drink any milk alternative fortified with vitamin D.

Sure, I'm not arguing against that. Just pointing out there aren't that many sources. And there are a lot of reasons people can't go outside whenever they want to, biggest one for me is it gets really cold during the winter. No way I'm going outside to hang out when it's 10 degrees outside.

If only humans could make their own vitamin D. Oh, wait

The major natural source of vitamin D is synthesis of cholecalciferol in the lower layers of the epidermis of the skin, through a photochemical reaction of UVB light, from the sun exposure (specifically UVB radiation) or UVB lamps.

Sure you can, but there's also winter months where you can't really go outside.

[–] bleistift2@feddit.de 2 points 1 year ago (1 children)

Thanks for pointing that out.

In the winter, only 10 percent of the body is exposed, and nearly 2 hours of sun exposure at noon is needed to produce a sufficient amount of vitamin D.

I thought less time was required.

So I'm supposed to be outside for two hours in -20 degree weather to get my Vitamin D just so I can survive?

There aren't? Fish right? Isn't that what fish and fish oil is all about? I think there are plenty of dietary sources of D3 beyond breast milk, if that's the issue.

[–] NocturnalMorning@lemmy.world 1 points 1 year ago (1 children)

Fish and eggs yes. But if you eat fish all the time, you'll find you have a different issue with mercury poisoning. Sources of vitamin D are low, so some foods and drinks get fortified with vitamin d. It isnt naturally found in anything but fish, beef liver, and egg yolk.

[–] Varyk@sh.itjust.works 0 points 1 year ago (1 children)

Eat fish oil instead of fish if you're worried about mercury.

As for d3 only being found in only a few foods? That can't be correct.

Nope, it isn't.

But you go on drinking milk if you like, people do lots of weird things.

Easily googled dude. It is true. Yes, we can also produce it from our skin, but lots of reasons people cant always go outside.

[–] Varyk@sh.itjust.works 3 points 1 year ago

It was easily Googled, and you are wrong.

[](other sources. )

Mushrooms, oranges, almonds, and we aren't even addressing the very cheap d3 supplements.

All other mammals not drinking milk past infancy: Am I a joke to you?

Literally all you need to do is touch grass a few times a week.

[–] vsis@feddit.cl 4 points 1 year ago* (last edited 1 year ago) (1 children)

that's not a good argument. Other animals doesn't cook food or wear clothes.

we do, since both things are older than our species, so we evolved this way. We'd die without cooking and clothes.

domestic animals and drinking milk are a newer thing, but our species do this weird things all the time.

that being said, vitamin D can be foud elsewhere lol

We have absolutely zero evolutionary need for milk past infancy. It's all culture and marketing.

Just because we do those things you mentioned doesn't mean they're necessary. In fact, I assure you, neither clothes nor cooking are strictly necessary for an individual's survival. They're convenient and comfortable, but not physiologically necessary. Obviously we'd freeze in cold climates, but there are plenty of places on earth we could survive well enough without.

We do need vitamin D to survive, but you can literally just get it directly from sunlight. The more time you spend inside, and the more thoroughly you clothe yourself, the more likely you are to need to supplement it. Simple as. You only need 30m outside 3x a week (2hrs in winter regions).

Another funny thing about milk, is that all the natural vitamin A and D is removed in processing. They literally have to re-fortify it again, so the only reason it's billed as this "healthy" thing is because it's basically a lab-made liquid vitamin.

We have absolutely zero evolutionary need for chocolate. It's all culture and marketing.

We have absolutely zero evolutionary need for coffee. It's all culture and marketing.

We have absolutely zero evolutionary need for beer. It's all culture and marketing.

You can apply that to virtually anything we consume that isn't plants or meat.

We have absolutely zero evolutionary need for Lemmy. It’s all tankies and linux users.

[–] Trainguyrom@reddthat.com 2 points 1 year ago

Hey now! I'll have you know that only about a third of my computers run Linux right now

Yes, exactly, now you're getting it! Glad we agree. The entire argument being made here is a purely normative one, not of necessity.
